Pontiac Repair: 1997 GRAND PRIX GTP, fuse boxes, blown fuses

Question
I LET SOMEONE TRY 2 INSTALL A STEREO AND THEY TRIED 2 RUN IT DIRECT. THEY RAN DOWN MY BATTERY, WHEN I GOTIT JUMPED AND STARTED IT, MY DASH COMPUTER, HEAT AND AC NO LONGER WORKED. WE GOT THE RIGHT PLUG THE STEREO STILL WOULDN'T WORK SO WE RAN IT 2 THE BATTERY. I CHECKED THE FUSES, ALL WIRES ARE CONNECTED SO I JUST WONDERED IF U HAD ANY IDEAS.

Answer
Hi heather:

make sure it doesn;t have any blown fuses that car has 2 fuse boxes one behind the glove box and one under the hood That is where I would look first. also make sure nothing was left unplugged Or possibly the wires that either run power or ground to those to items was taped into and or cut without seeing ti I can't tell you what happened. i can just tell you where to look.
Good luck :)
